Sensors – Why do Diesel Cars Have Issues With Sensors?

Diesel car sensors

Diesel cars have a higher likelihood of issues with sensors for a few reasons:

  1. Soot and particulate buildup: Diesel engines produce more soot and particulate matter than petrol engines. This can cause the sensors to become clogged or covered in a buildup of debris, which can affect their performance or cause them to fail entirely.
  2. High-pressure fuel system: Diesel engines have a higher-pressure fuel system than petrol engines. This can put more stress on the sensors, increasing the likelihood of failure.
  3. Higher operating temperatures: Diesel engines typically run at higher temperatures than petrol engines, which can cause sensors to degrade more quickly.
  4. Age and wear: As with any vehicle, sensors can wear out over time, particularly if the car is used frequently or driven in harsh conditions.
  5. Complex emission control systems: The sensors in diesel engines are an integral part of the emission control system, which can be complex and require frequent maintenance.

It’s important to note that diesel engines have improved in recent years and many of the sensor issues were related to older technology that did not comply with emissions regulations. Nowadays, the emission control systems in diesel engines are more advanced and reliable. Regular maintenance and inspections of the vehicle can help prevent or minimise sensor issues.
